The lawyer for the alleged attacker said his client was "very distressed" before the man was taken away in the back of a paddy wagon from The Rocks Police Station.

Earlier two other men were questioned by detectives and released without charge.

Just before 8.30am the pair met with their lawyers at Guylian Belgian Chocolate Cafe on George St. One of the men was accompanied by his father.

They soon entered the Rocks police station and spoke to detectives investigating the alleged bashing of the 26-year-old.

Mr Cramp was left in a coma as a result of the alleged attack.

After an hour at the station one of the men emerged with his lawyer saying his client had not been charged.

The second man also emerged from the station without any charges being laid.

Police said they are still investigating the attack and another alleged incident just moments before by the same group which also resulted in a man being hospitalised.

Last night, with his parents watching, CBD bash victim Simon awoke from his coma and whispered: "Hello mum, what happened to me?

Mum Angela said her son "looked at me" shortly after 5pm and spoke for the first time since he was battered to a pulp in an unprovoked attack in George St early Sunday."My husband (Phillip) and I held his hand and he squeezed our hands. We told him what had happened but he drifted back off to sleep. Yesterday we thought he was dead, now he's back with us. There is still a long way to go," said Mrs Cramp.

They have called for licensing laws in the CBD to change to stop drunken violence.Simon was with a female friend and a mate early on Sunday when he was punched by three drunken men.

"This should not happen in George St, in Australia," Mrs Cramp said outside St Vincent's Hospital, where her son is in a coma.

"He is a young man out with friends, totally innocent and now he's on life support." Mr Cramp wants something done to stop senseless attacks. "The Newcastle model seems to work with a 1am lockout and 3am shutdown. And late night food places seem to cause a lot of problems."

Laura Symes, 25, had flown to Sydney to see Simon for her birthday after the pair met overseas last year.

"To see what happened to him was just sickening," she said. "I heard the crack when his head hit the ground and saw the blood, we thought he was dead."

The 26-year-old from Cremorne Point came out of his coma briefly yesterday. "When I put my hand in his he curled towards me. He responded and as a mother I can tell you Simon knew I was there. I just burst into tears," Mrs Cramp said.

Doctors said it would be days before they could assess the damage to his brain.

Both parents believe it's time for zero tolerance on Sydney streets.

"This thug would have been in trouble before and hasn't been dealt with and thinks he can get away with it," Mrs Cramp said. "The courts need to send a message that you cannot go around hitting people for entertainment."

Lord Mayor Clover Moore said she would discuss the attack with police

"On Thursday I'm hosting a roundtable forum in Town Hall with police to discuss safety in our city," she said.

Strike Force Pamdala detectives last night released CCTV images of three men and three women they want to talk to about the attack.
